  • http-destination: Users now can specify the action for any HTTP result code.
    Use with response-action(response_code => action) in your http block.
    Available actions are: success, retry, drop and disconnect. (#3007)
  • syslog-ng-cfg-db: Added a new script, which can provide the options of
    sources and destinations queried by the user. This tool can make the configuration
    of syslog-ng a lot easier. Use with ./ from the
    contrib/config_database dir.(#2997)
  • redis-destination: Improved the performance by 2 orders of magnitude.
    In our labor environment, now it operates at 25k EPS. (#2972)


  • create-dirs(): Added to pipe() source/destination, and standardize the behavior.
    (#3018, #2635)
  • default-network-drivers: Added max-connections() option, to change the limit
    from 10. (#2961)
  • checkpoint: Added support for timezone value at the end of timestamps. (#3033)
  • filter/rewrite: Added disable-jit flag to disable JIT PCRE compilation. (#2992, #2986)
  • syslog-ng-ctl: Added export-config-graph option to visualize config graph. (#2990)
  • build/travis: Added ARM64 arch support. (#2967)
  • build/dbld: Readded CentOS 6 support. (#2860, #2971, #3028)
  • python: Added Python 3.8 support. (#3017)


  • tls: Fixed an infinite loop which occured, when a TLS connection broke. (#3026, #3009)
  • log-block: Fixed an issue, where inline network destinations disjointed
    the rest of the config. (#2989, #2820)
  • kafka/network-load-balancer: Fixed a crash when an argument was set to empty. (#3002)
  • python-source: Fixed a memory corruption during reload. (#3014)
  • python-destination: Actually use return value of open method. (#2998, #2513)

  • python: Fixed python Exception reporting when no Exception happened. (#2995)
  • telegram: Fixed the syntax error of the use-system-cert-store() option. (#2977)
  • config: Throw error to single dots, which were ignored before. (#3000)
  • file-destination: Delay ACKs until messages are written to disk. This fixes message
    drop on I/O error and message lost in the LogProtoFileWriter in case of a crash, by
    retrying to send the message. (#2985)
  • http-destination: Handle global template options values. (#3020)
  • timeutils: Fixed month and day name parsing, when only the first 2 characters
    matched. (#3035)

    created without initial parsing. (#2974)
